HENRY BODENSTEIN, OF ARLINGTON, MASSACHUSETTS.

ICE-CUTTER.

SPECIFICATION forming part of Letters Patent N 0. 729,122, dated May 26,1903.

Application filed July 17, 1901.

To aZZ whom it may concern:

Be it known that I, HENRY BODENSTEIN, a citizen of the United States,residing at Ar-' lington, in the county of Suffolk and State ofMassachusetts,have invented certain new and useful Improvements inIce-Cutters, of which the following is a specification.

My invention relates to improvements in ice cutters or plows, and refersparticularly to an improved construction of tooth to be used on thecutter or plow.

One object of my invention is the provision of a tooth which can beeasily and readily applied and used upon the form of plows or cutters ingeneral use.

Another object of myinvention is the provision of a tooth which can beeasily sharpened and which will receive the force or strain imposed incutting in a proper manner without damage to the tooth.

Another object of myinvention is the provision of a tooth which can beeasily sharpened, which will perform the operation of cutting in aperfect manner, which can be adjusted to the work, and which will besimple, inexpensive,and durable in construction and thoroughly efficientand practical for the purposes intended.

To attain the desired objects, my invention consists of a tooth for icecutters or plows embodying novel features of construction, substantiallyas disclosed herein.

Figure 1 represents a side view of an ice plow or cutter, the bladesbeing provided or equipped with my improved tooth. Fig. 2 represents aside view of a portion of one of the blades provided with my tooth, theview being on an enlarged scale. Fig. 3 represents a similar View of aslightly-modified construction. Fig. 4 represents a detail view of theparts detached. Fig. 5 represents a sectional view of a modified form offastening, and Fig. 6 is a sectional view of a tongue-and-grooveconnection.

In the drawings, Adesignates' the frame of a plow or cutter providedwith the handles B at one end and with a suitable draft attachment O atthe other end, and secured to the frame and depending therefrom are theblades or cutters D of the plow. The blades are formed with the heel Eand with the adjacent kerf or recess F, forming the inclined Serial No.68,601. (No model.)

edge G along the lower face of the blade. The said inclined face isprovided with teeth or serrations H, and above the same on each side ofthe blade is formed a groove or channel J, and this construction allowsthe application of my improved form of tooth. The purpose of the heel oneach cutter is to form a stopor abutment for the cutter when the heelcontacts with the ice, and thus the heel prevents thedetachable teethfrom striking the ice or from going too deep into the ice.

My tooth consists of the bottom wall K, formed at its forward portionwith the cutting edge K, and the side walls K which are formed at theirupper end with the flanges or guides K which fit snugly in the groovesor channels of the blades and are adapted to be held at any desiredadjustment with reference to the blades by the pin or stud L, whichpasses through the side walls of the tooth and has its upper face formedwith serrations L, which engage the serrations of the blade and, as isevident, secure the tooth perfectly to the blade and at any desiredadjustment with reference to the blade. Fig. 6 I have shown the toothand blade as connected by a tongue-and-groove connection.

I claim 7 1. In an ice-cutter, the combination with the blades havingthe lower downwardly and forwardly inclined serrated edges and thegroove on each face parallel with said edge, of the teeth embracing saidserrated edges and having inward-extending flanges fitting in saidgrooves and means passing through the teeth and engaging the serrationsof the blades to hold the teeth at the proper adj ustment on the blades.

2. In an ice-cutter, the blades formed with the depending heel portion,the lower serrated edge and the grooves on each side above the serratededge,the teeth fitting on the'lower edge of the blade and having theflanges fitting the grooves, and the toothed pin passing through theside walls of the teeth and engaging the serrations on the blade to holdthe teeth at the desired adjustment, said transverse pin having a smoothface fitting the tooth and a serrated edge engaging the blade proper.

3. In an ice cutter or plow, the combination of a frame, handles carriedby the frame,

andaseries of blades or cutters secured in the frameysaid cutters beingeach formed with a heel portion and a contiguous inclined lower face, aseries of teeth on said lower face and a groove or channel on each sideof the blade parallel with the teeth,a detachable tooth having a forwardcutting edge and provided with flanges fitting in the grooves of theblade for adjusting the tooth on the blade, and means for holding theteeth at the desired adj ust- Io ment.

In testimony whereof I aflix my signature in presence of two witnesses.

HENRY BODENSTEIN.
